We are developing our infrastructure in response to climate, population and lifestyle changes so we can deliver a service customers can rely on now and in the future. Section 82 mandates the continuous monitoring of water quality upstream and downstream of storm overflows and wastewater treatment assets, with the objective of improving transparency, compliance, and environmental outcomes. The CWQM programme is a major transformation initiative requiring significant investment in technology, installation capability, ecological and hydrological planning, and real-time data assurance. United Utilities requires a Supplier capable of delivering a robust monitoring solution that integrates with UU's existing telemetry, data platforms, operational processes, and regulatory reporting frameworks, ensuring accurate monitoring and near-real-time data availability. United Utilities are looking to procure the end-to-end delivery, operation, and assurance of Continuous Water Quality Monitoring (CWQM) across United Utilities' (UU's) waste water network, in accordance with the requirements of Section 82 of the Environment Act and the CWQM Interim Technical Standard, as updated from time to time. Under the Agreement, a CWQM Supplier shall provide all goods, works and services, including but not limited to: * All hardware, including sondes, remote telemetry units, batteries, fixings, kiosks and other installation options; * Design & Installation process including all associated works including all associated works required to install/maintain equipment such as (but not limited to): land clearance, civils work and surveys; * Data acquisition and provision; * Maintenance and calibration; * System integration with the Company's systems; * Reporting capabilities; and * Any other goods and services required to ensure continuous, accurate, reliable, and regulatory-compliant monitoring at designated upstream and downstream locations.",

This will be followed by an ITN and BAFO stage, which will assess the trial and commercial offerings. Phase 1 - ITT - Trial Selection - This stage will allow for the down selection to 4 suppliers to take part in the 9-month trial. The trial will be undertaken on a fixed price basis, set by UU based on market intelligence and benchmarking. Phase 2 - ITT - Tender Negotiation - will run in tandem with the trial and will mirror a traditional ITN stage. The Bidder will be assessed against Commercial and Technical element along with technical criteria for the trial. Phase 3 - BAFO - This phase will be post-trial and will be solely based on the assessment of the Bidder's submitted prices for their Best and Final Offer. The number of Bidders for each Phase is as follows: No. of Bidders to Phase 2 - 4 No. of Awards 1* United Utilities currently intends to make a single award to one CWQM Supplier. However, reserves the right to make two awards, and enter into two separate Agreements. The reasons for making two awards rather than one may include Regulatory change or Scalability and delivery risk."
